atan2(y, x) returns the angle θ between the positive x-axis and the ray from the origin to the point (x, y), confined to (−π, π].Graph of (,) over /. In computing and mathematics, the function atan2 is the 2-argument arctangent.

[1] [2] All functions use floating-point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions. Most of these functions are also available in the C++ standard library, though in different headers (the C headers are included as well, but only as a deprecated compatibility feature).
In engineering problems, especially in the area of solar energy application, the solar azimuth angle, which can be computed from the x- and y-component of the vector pointing to the Sun using the atan2 function, normally measures from due North (positive y-axis) or due South (negative y-axis), this can be achieved by using atan2(x, y) or atan2 ...
